Commercial MIMO OTA Emulator Targets Mobile Terminal Testing
According to the company, the Propsim F8 from Elektrobit (EB) is the industry’s first commercially available multiple-input multiple-output (MIMO) over-the-air (OTA) emulator to increase the performance and data rate of MIMO mobile terminals. With it, designers can benchmark the performance of their mobile devices for quality of service (QoS), data throughput, latency, and spectrum availability to select the best devices needed to address the growing adoption of applications that demand higher data rates such as the ability to download graphics, play games, and watch video.
Traditionally, OTA testing focused on single-input single-output (SISO) devices by only measuring power and antenna efficiency. With MIMO OTA testing, designers can assess the true performance of the terminal as a whole. It also lets them evaluate different designs in a fully repeatable and realistic wireless network environment so they can test all critical parts of the mobile terminal design at once, including antennas, the RF front end, and baseband processing. This eliminates the need for cables and test connectors, leaving the mobile device intact and providing more accurate results of how the device will perform in a real-world environment.
The EB Propsim F8 MIMO OTA emulator is designed to meet the conformance and beyond-conformance testing requirements of WCDMA, HSPA, 3GPP, Long-Term Evolution (LTE), WiMAX, and wireless local-area networks (WLANs).
